Cloudflare Web Application Firewall Reviews

As a senior enterprise architect, I work on solution developments using Cloudflare Web Application Firewall, and the other teams of our organization, such as the administration team, perform the daily or BAU activities.

The solution's WAF use case provides protection against DDoS and data injection activities. Cloudflare Web Application Firewall is also utilized for internet-connected applications. One of our organization's customers leverages the solution with the SASE platform for zero-trust security. 

There is a huge signature repository in Cloudflare Web Application Firewall. Whenever there are any new vulnerabilities and attacks, the solution logs it within around 48 hours. There are built-in signatures in the tool, especially for identifying the source and blocking DDoS attacks immediately.  

We use this solution to protect our websites and services.

The solution prevented several attacks, such as Log4j two years ago when it emerged as a major vulnerability. 

Cloudflare Web Application Firewall released protective rules a few hours after we discovered the potential problem and provided protection.

I mainly use it for routing and then for monitoring the firewall.

We saw some improvements in our website security or our network security.

Rulesets are kind of majorly used for subdomain routing and rate limiting. When we expose our API, so we need to evaluate their use cases.

I use the product for securing web applications and providing DDoS protection from the Internet and malicious users.

The rate limiting features and customizations in terms of URL match and applying policies are valuable to me. The custom rules and the geo-redundant geographical rule feature, which allows me to implement geographical rules for customers, add significant value. 

Additionally, operational manageability is a major benefit for me. Cloudflare is self-sustained instead of requiring on-premises equipment that needs regular updates and maintenance.

I am using Cloudflare Web Application Firewall to develop web applications and mobile applications for a business belonging to the manufacturing industry which wishes to migrate its entire applications from its existing AWS system to Cloudflare.

The enterprise bundle includes a variety of features, such as a Web Application Firewall, rate limiting, CDN, DDoS protection, remote management, performance monitoring, and more. It is a really nice product.

I use Cloudflare as a reverse proxy in front of our web part. It is crucial for hiding all traffic with Cloudflare's standard WAF.

For us, the key feature of Cloudflare is DDoS protection and IP hiding, especially since we are a crypto company. We also use rate limiting, particularly for our APIs. Furthermore, we utilize Cloudflare's CDN (cache) functionality, which is not related to security, so I initially skipped mentioning it.

The main use cases for Cloudflare Web Application Firewall (WAF) are to protect organizations from attacks by bad actors and hackers. We have a process for this, where we first whitelist employees and third-party clusters to prevent attacks. 

Then, we divide WAF into three main sections: WAF Protect score, WAF score, and threat score. We also make adjustments based on the specific needs of each organization. These are the general steps at a high level. 

Cloudflare WAF is a comprehensive system with many aspects and in-depth documentation that can be tailored to specific client requirements. 

The use cases vary depending on the client, whether they are retail or banking sectors, as each has different needs and requirements. We maintain the WAF configurations based on these specific needs.

There are many incidents we handle daily. We have a large client. We implemented rate limiting and deployed a worker in correlation with the WAF to protect their API endpoints regarding pricing and inventory. 

We successfully mitigated a bot attack with that combination of measures for our customer recently. It is one of the successful mitigation.

Cloudflare is very flexible.

We use the solution for the web application firewall.

The solution protects our application, which runs on the HTTP protocol, from DDoS attacks.
